What is the effect of ball mill diameter on the rate of. - ResearchGate

François K. Mulenga. University of South Africa. Dear Philbert. In order to understand the effects of ball mill diameter on the selection function, you need to have a look at Austin's scale-up model and interpret it accordingly. Attached is my recent paper that provides a description of the scale-up model (see Equations 8 to 13).

Ore Grinding Mills - 911 Metallurgist

Mar 18, 2017 . Ore Grinding Mills are used for the fine grinding as the last step in the reduction of an ore prior to concentration (gravity or flotation) or cyanidation. Practice varies, depending upon the type of ore and the amount of reduction required. In addition, some of the older properties continue with methods that.

The Effect of Ball Size Diameter on Milling Performance | OMICS .

Johannesburg Gauteng,South Africa Tel: 0117177522 .. The 30 mm ball diameter milling still performed better than the small ball diameters, but the performance for this ball size had decreased for the -2 mm +1.4 mm mono-size feed compared to the bigger -4 mm +2.8 mm mono-size feed. This therefore shows that should.
